Device for treating particles having a vortex chamber defined by end walls at both ends and a circular wall, a rotation imparting device with a fluid feeder arranged in a mainly tangential direction, a particle outlet and a central fluid outlet, an auxiliary chamber coaxially arranged with the vortex chamber defining a treating zone, which auxiliary chamber has a circular outer wall and an end wall and opens into the vortex chamber through an opening in the end wall of the vortex chamber opposite the central fluid outlet, a device for injecting particles coaxially into the treating zone, and a device for feeding a treating fluid into the treating zone in mainly axial direction, wherein the ratio of the area of the opening to the cross-sectional area of the vortex chamber is less than 0.50.

Device for treating particles in a rotating fluidized bed

A vortex chamber device comprising: The invention also provides a method for treating powder particles or a powder particles precursor.

Vortex chamber device, and method for treating powder particles or a powder particles precursor

A device for discharging, through a central rotating chimney, fluids from a fluidized bed driven in a rotational movement in the same direction by the rotation of the outer circular wall of a reaction chamber and/or by injection of part of these fluids along the circular wall of a fixed or rotating chamber, and methods for catalytic polymerization, drying, or other treatments of solid particles in suspension in a rotating fluidized bed or for cracking or other catalytic conversions of fluids using this device.
